At a court hearing later that week the hoaxer, described by her lawyer as an “injured woman” who had been married for 22 years, said she only wanted to get revenge on her rival and “hadn't calculated the consequences” of her actions.

In addition to the three months' prison sentence handed down in July, the woman will now receive a bill for 90,000 francs from Geneva police, Swiss media said on Friday, reporting information received by Le Matin.

Geneva police chief Francois Waridel said the amount “corresponded to 145 police officers working at 100 francs an hour as well as the cost of meals, drinks and two police dogs”.

In total the bill covers 880 hours of work between the evening of July 26th and the following afternoon, said the paper.
